• Develop and evaluate MF, UF and ion-exchange membranes through membrane casting, phase inversion, coating and performance testing.
• Develop and optimize polymer formulations, membrane coatings and functional materials.
• Conduct membrane and material characterization studies for permeability, selectivity, fouling resistance and durability.
• Operate laboratory and pilot-scale systems for membrane filtration, ion exchange, adsorption and electrochemical processes.
• Perform water and wastewater analysis including pH, conductivity, TDS, hardness, alkalinity, turbidity, COD, BOD and TOC.
• Support membrane fouling, cleaning, regeneration and CIP studies.
• Analyse data and prepare technical reports, SOPs, test procedures and presentations.
• Assist in pilot trials, commissioning, technology scale-up and performance evaluation activities.
• Maintain laboratory equipment, calibration records, inventory and safety compliance.
• Collaborate with internal teams, suppliers and external laboratories to support R&D activities.

Required Knowledge & Skills

• Strong fundamentals in polymer, physical, analytical and inorganic chemistry.
• Hands-on experience in membrane fabrication, polymer formulation, coatings or water treatment R&D.
